So I had a tech 2 stolen. My buddy has one and we can’t find the serial number in his settings. Someone has one local for sale and I wanna look at it. I’m prepared for the possibility of the serial number missing on the back. We tried my buddy’s tech 2 and can’t find the serial number in the settings tool screen anywhere. Is there anyway to find the serial number like hooked to tis through gm or Saab etc website? Please help I will pay you for your time via PayPal. Thanks.
